[Treatment of spinal cord arteriovenous malformation by surgical excision combined with afferent vessel coagulation-report of a case (author's transl)].

A case of spinal cord arteriovenous malformation was reported, in whom serial selective spinal angiogram and pantopaque myelogram showed a successful demonstration of intramedullary nidus. A 25-year-old male was admitted with paraparesis, impotence, hypesthesia and hypalgesia in his legs in 1974. He was diagnosed to have a spinal cord arteriovenous malformation of so-called "glomus type" with intramedullary nidus by the selective spinal angiogram and pantopaque myelogram. The nidus was fed by the anterior spinal artery through the 8th intercostal artery, from which a major draining vein extended caudally, but there was also some cranial drainage. The arteriovenous malformation was treated by surgical excision combined with afferent vessels coagulation in order to prevent the rupture of the remaining intramedullary nidus. After operation the patient develop a transient analgesia and girdle pain at T9-10 level, but after 42 days he regained full muscle power in his legs and could run by himself, while sensory disturbance remained about the same as before surgery.
